Optimal Operation Models of Pumped Storage Power Station

Tow optimal operation models of pumped storage power station are presented.One is a single optimal operation model,in which are considered the benefit loss of the pumped storage power station in the case of its capacity being more or less than the power system demand and the forced outage rate of the pumped storage power station units.The other is a whole process joint optimal operation model of pumped storage power station,in which the ability of modulating the output of thermal power units is taken into account.A quantitative method for curve fluctuation is proposed.
